ZENA EGKELBARGER, PF GOSHEN, INDIANA l J anraonucnn,

To 'all 'whom it mag concern:

Be it known that I, ZENA EcxnmsAnenn, a

citizen of the United States, residin at Goshen, in the county of 'Elkhart and tate of Indiana, have invented new and useful Improvements in Reproducers, of which the following is a specification.

My present invention pertains reproducers for use "m sound-reproduclng machines, and is a continuation of my contem porary application filed June -16, 1917, Serial Number-17 5,205. o

The reproducer consists in the peculiar and advantageous construction, novel combinations and adaptation of parts hereinafter descr bed and definitely claimed.

In the accompanying drawings, which are hereby madea parthereof:

2'0 ance with my invention. I

Figure 1 is a side elevation showing a portion of a tone arm constructed in accord- Fig. 2 is a vertical section of the same.

' Fig. 3 is a cross-section, takenin the plane indicated by the line 33 of Fig. 1.

Fig. 4 is a detail view of the arm section 5. Similar numerals of reference designate corresponding parts in all the views of the drawings.

The tone arm portion 2 that reaches laterally from the usual upright portion is adapted at its forward end 3' to receive a rounded portion or ball 4 on the rear end ,ofthe section 5 that is interposed between the portion 2 and the sound box 6.

At this point I would have it understood .that the sound box 6 per 86 may beof the I construction shown or of any other approved .type though the specific sound box illustrated,. equipped with the stylus construction claimed invmy tion filed June 19, 1916, SerialNo. 104,433, is well adapted for use in conjunction with my improved tone arm.

In furtheranceof my present invention the rear end portion of the section 5" is reduced forming anannular shoulderthereon and its outer end is screw-threaded for the reception of a threaded collar4F, thereby forming a circumferential recess between said collar and shoulder, and into said recess is fitted an annular ball '4, a wave spring 5, being interposed between the ball and collar to preventtoo free movement of the ball around the section 5, and I' would .have it understood that the said ball andits contemporary applica-' Specification of Letters Patent.

, complementary socket 3 and spring 5 constitute important "features ofv the invention.

Formed in the circumference of the sec tion 5 is a groove 7 which extends through about one-fourth of said circumference. The portion 2 is provided at diametrically opposite points 'Wlth threaded apertures 8 for the engagement of screws 10 which bear loosely 1n apertures in the ball 4. One screw ex-.

tends into the groove in section 5 and permits of limited movement of the same and the parts carried thereby so that the reproducer can be readily changed from use on the Edison-type of record for use on the Victor type, and vice versa.

By virtue of this construction the sections 2 and 5 are simply," strongly and adjustably connected together, and also in such manner that the'sections 5 and 6 are free to move upwardlyand downwardly;

The"'connection between the section-5 and the sound box and its appurtenances are clearly illustrated in Fig. 2, and by refer ence to said figure it willbe understood that the depending portion of the section 5 1s shouldered at 10 and exteriorly threaded at 11. The sound box 6 is bored'to snugly receive the depending portionof section 5 and to enable the sound box 6 to abut against the shoulder 10, and said sound box reproducer to either the hill and vale type of record or the laterally-waving groove type of record.

To limit the movement of the sound box about the depending portion of the section 5,

a stop slot. 15 is cast in the top of the sound box and a stop pin 16 is carried in the end of the section .5 and so as to move in the said slot 15.

40, 40 are stop lugs on the bottom and one side of the section 5. The said stop lugs serve by bringing up a ainst the end of the section 2 to prevent t e repro'ducer from ent, is:

. entialrecess formed at its reduced outer threaded end portion, or threaded collar secured to said outer threaded end portion, an annular ball disposed within said recess between the said collar and an annular shoulder formed at the reduced :end portion and disposed within the end of the first named section, a spring interposed between the ball and collar to prevent too free movement of the ball, and oppositely disposed screws threaded in the first section and fitted into the apertures of the ball, one

screwextendin into an'opening; formed in 2o the reduced en of the second section. 2. In a tone arm, the combinatlon of a] section having an exterior shoulder and a threaded end, a sound box bored to receive said section and arranged to abut against 25 J said shoulder and having a chamber, a nut arranged inthe chamber 'of the box and on the threaded portion of the section, and a spring Washer disposed within the chamber in contact with the rear face of said nut.

In testimony whereof I have hereunto set my hand in presence )of two subscribing w1tnesses.-
